بهبود رشد، عملکرد و کارآیی مصرف نیتروژن تحت رژیم های مختلف نیتروژن در گیاه دارویی مریم گلی با کاربرد زئولیت

Due to the low efficiency of nitrogen (N) because of losses through leaching which also causes environmental pollution, it is necessary to use a suitable managemenpractices for nitrogen fertilizer application to minimize nitrogen losses through leaching. Sage is one of the most important and economical medicinal plants in the world. In order to investigate the application of zeolite to improve growth, yield and N use efficiency in Sage, the experiment was laid out as a factorial, randomized complete-block design with three replicates in ۲۰۱۸. Experimental treatments including N fertilizer (from urea source) at three levels (zero, ۷۵ and ۱۵۰ kg N ha-۱) and zeolite at two levels (without zeolite and ۱۰ t ha-۱) were investigated. The highest plant height ۱۹.۹۰ cm, the number of lateral branches ۱۹.۸۷ per plant and the leaf area ۱.۳۸ cm were observed in the application of ۱۵۰ kg N ha-۱ and ۱۰ t ha-۱ of zeolite. The results showed that the zeolite application was able to help increase the yield of sage by N so the highest fresh and dry yield were observed of ۱۵۰ kg N ha-۱ and ۱۰ t ha-۱ of zeolite, ۱۱۱۴۴ and ۲۹۵۱ kg/ha, respectively. The highest soil and plant N concentration were ۰.۱۴ and ۲.۸۲ % in the treatment of ۱۵۰ kg N ha-۱ and ۱۰ t ha-۱ of zeolite. The highest N uptake was ۸۶.۳۰ kg/ha in application of ۱۵۰ kg N ha-۱ and ۱۰ t ha-۱zeolite, and the highest N use efficiency was ۱۱.۵۳ kg/kg in the application of ۷۵ kg N ha-۱ and ۱۰ t ha-۱ zeolite. The highest essential oil content and yield were ۰.۸۴% and ۲۱.۰۲ kg/ha, in the application of ۱۵۰ kg N ha-۱ and ۱۰ t ha-۱ zeolite. Based on the results, it can be concluded that the application of zeolite was able to prevent the growth, yield of soil N and efficiency of N consumption in the Salvia officinalis by preventing the leaching increasing its absorption and preventing the contamination of groundwater, and also reduce energy consumption.
